Operation Yellow Jacket is a partnership between PennDOT and the Pennsylvania State Police. Troopers dress like PennDOT workers to monitor the speed of motorists to ensure the safety of workers and motorists in work zones. Motorists should remember, the next time they see a PennDOT worker in the work zone, they could be a trooper monitoring speed.
